Abstract: One or more embodiments of a respirator that includes a polymeric netting is disclosed. The respirator can include a mask body including a perimeter, a harness attached to the mask body, and a face seal disposed adjacent at least a portion of the perimeter of the mask body. In one or more embodiments, the face seal includes a polymeric netting including polymeric ribbons and polymeric strands, where each of the polymeric ribbons and strands having a length, width, and height, where the length is the longest dimension, the width is the shortest dimension, and the height is the dimension transverse to the length and the width. The polymeric ribbons have a height-to-width aspect ratio of at least 5 to 1, a major surface that is intermittently bonded to only one polymeric strand, and a height that is at least two times greater than a height of the one polymeric strand.

Abstract: A respirator (10) that has a mask body (12), a harness (13), and an exhalation valve (14). Both the harness (13) and the exhalation valve (14) are secured to the mask body (12). The exhalation valve (14) comprises a valve seat (20) and a flap (22) that has a surface (57) that has been ablated. Through use of an ablated flap, the flap characteristics can be better fashioned to achieve desired valve performance. The valve flap can be fashioned to remain closed under any orientation but also to open with minimal force or pressure from the wearer's exhaled air. A valve having these qualities provides a respirator that is more comfortable for a person to wear, which can be particularly beneficial to workers who wear respirators for extended time periods.

Abstract: The present invention relates to a sealing strip, a respirator, and a method for manufacturing a sealing strip. The sealing strip includes a main body part, the main body part having an upper surface, a lower surface, a first side surface, and a second side surface opposite to the first side surface. The main body part includes a curved surface part. The curved surface part includes a first convex part and a second convex part, and the first convex part and the second convex part are connected to each other in the lengthwise direction of the sealing strip to define a concave part located therebetween. The concave part is configured to accommodate the nose of a wearer. The first convex part and the second convex part are symmetrical about the concave part. A first side surface of the curved surface part is a sinusoidal curved surface with a constant amplitude extending in the lengthwise direction of the sealing strip. By the sealing strip, the respirator and the method for manufacturing a sealing strip according to the present invention, a manufacturing process of the sealing strip can be simplified; a maximum utilization rate of materials can be achieved; sealing between the respirator and the face of the wearer can be improved, and the wearing comfort of the respirator can be increased.

Abstract: The present invention relates to a sealing foam, a respirator, and a method for manufacturing a sealing foam. The sealing foam includes: a main body part, the main body part being a porous foam; an air-proof film on a continuous surface; and an anchor layer, the anchor layer being continuously provided on the upper layer of the main body and provided between the air-proof film and the main body part, and the anchor layer being partially embedded in pores of the porous foam. The respirator includes a respirator main body and a sealing foam of the present invention. The method for manufacturing a sealing foam includes: providing a porous foam to prepare a main body part of a sealing foam, and providing an anchor layer and an air-proof film on the porous foam, so that the air-proof film is continuously provided on an upper surface of the main body part, wherein the anchor layer is provided between the air-proof film and the main body part, and is partially embedded in pores of the porous foam. The sealing foam, the respirator, and the method for manufacturing a sealing foam according to the present invention are convenient for subsequent cutting, can simplify the manufacturing process of the sealing foam, improve the sealing between the respirator and the face of a wearer, and improve the wearing comfort of the respirator.

Abstract: Various embodiments of an exhalation valve and a filtering face mask that includes such exhalation valve are disclosed. The exhalation valve can include a valve seat and a valve flap disposed over a seal surface and an orifice of the valve seat. The valve flap is adapted to be sealed against the seal surface of the valve seat when the exhalation valve is disposed in a closed configuration such that fluid is prevented from flowing through the valve seat. The orifice of the valve seat can include a substantially circular shape in a plane defined by a first major surface of the valve seat. Further, the seal surface can circumscribe the orifice and can include a substantially noncircular shape in the plane defined by the first major surface of the valve seat.

Abstract: A valve (14) that includes a valve seat (20) and a flap (22) that has a surface (57) that has been ablated. Through use of an ablated flap, the flap characteristics can be better fashioned to achieve desired valve performance. The valve flap can be fashioned to remain closed under any orientation but also to open with minimal force or pressure from the flow stream. A valve having these qualities provides a valve can operate more efficiently, which may be particularly beneficial when used one respiratory masks where the valve is powered by the wearer.
